Description

Technical Field

[0001] The present application relates to the technical field of clothing processing equipment, and in particular to a clothes dryer. Background Art

[0002] A clothes dryer is a clothes processing device used to dry clothes. It is usually divided into direct-discharge clothes dryers, heat pump clothes dryers, etc. according to its working mode. The drying air of a direct-discharge clothes dryer is directly discharged into the air after passing through the drum, while the drying air of a heat pump clothes dryer circulates in the entire air circulation system.

[0003] During the clothes drying process, when the high-temperature airflow passes through the surface of the clothes to be dried in the drum, some fine lint will be brought out. When the lint flows with the drying air, it may cause air duct blockage or secondary pollution to the clothes. Especially for heat pump dryers, if the lint enters the air duct, it may be adsorbed on the condenser, evaporator or circulating fan, causing problems such as low operating efficiency or failure of the heat pump system, and increasing the difficulty of cleaning the dryer. Therefore, existing dryers are usually equipped with a filter component for filtering lint.

[0004] The filter component can filter out lint, but after working for a long time, the lint will gradually accumulate inside the filter component, which will clog the filter inside the filter component, causing the circulating air duct to be blocked. As a result, a good circulation cannot be formed in the entire air circulation system, resulting in low ventilation volume, low drying efficiency and other problems. Utility Model Content

[0047] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0048] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0049] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0050] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0051] For the heat pump dryer 10, it is necessary to use a filter assembly 400 to filter the lint or other impurities in the air circulation system to prevent the lint or other impurities from entering the evaporator, condenser and circulating fan 800, causing problems such as low operating efficiency or failure of the evaporator, condenser and circulating fan 800. However, after the filter assembly 400 has been working for a long time, the lint or other impurities will block the air outlet of the filter assembly 400, causing problems such as low air outlet efficiency of the filter assembly 400, reducing the air volume entering the evaporator, condenser and circulating fan 800, and further reducing the air volume entering the drying barrel 200, which also causes the problem of poor drying effect. Therefore, in order to prevent the lint or other impurities from blocking the air outlet of the filter assembly 400, the present application proposes a dryer 10.

[0052] For the clothes dryer 10, for ease of understanding, the direction in which the user faces the operation panel of the clothes dryer 10 is defined as the front side, because usually, the user will stand in this direction to interact with the clothes dryer 10, such as putting clothes in and operating the control panel. Accordingly, the direction in which the user faces away, i.e., the other side of the clothes dryer 10, is defined as the rear side.

[0053] See also Figures 1 to 5 As shown, the clothes dryer 10 includes a housing 100, a clothes drying barrel 200, a circulating air duct 300, a filter assembly 400 and a collection assembly. The housing 100 is in the shape of a cylinder extending up and down, and is rectangular as a whole; of course, it can also be in other shapes, such as a circle, a diamond, etc., which is not limited here.

[0054] See also Figure 1 As shown, the housing 100 includes a front support shell 110, a base 120 and a rear cover 130. The front support shell 110 is located at the front side of the dryer 10, and the rear cover 130 is located at the rear side of the dryer 10. The front support shell 110 and the rear cover 130 are both perpendicular to the base 120. The front support shell 110 and the rear cover 130 are connected through the base 120 to support the front support shell 110 and the rear cover 130. In addition, the base 120 is also in contact with the ground. It is understandable that the base 120 can be equipped with parts such as feet that protrude downward and contact the ground, so that the base 120 as a whole has a certain gap with the ground to ensure the drying effect of the base 120; the base 120 can also be equipped with sliding rollers to facilitate the movement of the dryer 10.

[0055] See also Figure 1 As shown, the clothes drying barrel 200 can be rotatably arranged in the housing 100 for drying clothes. The clothes drying barrel 200 can adopt a cylindrical structure, and its two opposite ends in the axial direction are respectively connected to the front support shell 110 and the rear cover 130 of the housing 100. The front support shell 110 and the rear cover 130 both support the clothes drying barrel 200 to ensure the stability of the clothes drying barrel 200 in the housing 100. The clothes drying barrel 200 is provided with a clothes feeding port on one side close to the front support shell 110, and the housing 100 is also hinged with a door body, which can be used to close the clothes feeding port. When the door body is opened, the user can put clothes from the clothes feeding port into the clothes drying barrel 200. When the door body is closed, the clothes dryer 10 can be in the clothes drying program.

[0056] See also Figure 1As shown, the gas in the circulating air duct 300 circulates inside the dryer 10 to dry the clothes in the drying barrel 200. The circulating air duct 300 includes a bottom air duct in the base 120 (not shown in the figure), a rear air duct between the drying barrel 200 and the rear cover 130 (not shown in the figure), a drying air duct inside the drying barrel 200 (not shown in the figure), and an outflow air duct from the front support shell 110 to the base 120 (not shown in the figure). That is, after the gas is heated by the heating system described below, the gas is drawn from the bottom air duct to the rear air duct by the circulating fan 800 described below, and then enters the drying air duct inside the drying barrel 200 from the rear air duct. At this time, the gas dries the clothes in the drying barrel 200, and the gas after drying the clothes enters the base 120 again from the outflow air duct for heating, and this reciprocating process is used to dry the clothes. That is, the air flows through the base 120, the rear cover 130, the drying tub 200 and the front support shell 110 in sequence, and the air flowing through the front support shell 110 passes through the base 120 again to circulate and dry the clothes.

[0057] See also Figure 3 and Figure 5 As shown, the filter assembly 400 is disposed in the circulating air duct 300 and can be disposed on the front support shell 110 , which can be used to filter the lint or other impurities brought out of the gas from the drying barrel 200 to prevent the lint or other impurities from entering the heating system in the base 120 .

[0058] See also Figure 6 and Figure 8 As shown, Figure 6 A schematic diagram of the decomposed structure of the filter assembly 400 is shown, and the filter assembly 400 includes a first filter frame 410, a second filter frame 420 and a third filter frame 430. The third filter frame 430 can perform a first filter on the airflow coming out of the drying barrel 200, the second filter frame 420 performs a second filter on the airflow coming out of the drying barrel 200, and the third filter frame 430 performs a third filter on the airflow coming out of the drying barrel 200. The airflow with lint coming out of the drying barrel 200 is filtered three times by the filter assembly 400 to ensure the filtering effect of the filter assembly 400 on lint, prevent the lint from entering the evaporator, condenser and other structures, and ensure the normal operation of the dryer 10.

[0059] Among them, a first accommodating cavity is formed inside the first filter frame 410, the second filter frame 420 is arranged in the first accommodating cavity of the first filter frame 410, a second accommodating cavity is formed inside the second filter frame 420, and the third filter frame 430 is arranged in the second accommodating cavity of the second filter frame 420, and a third accommodating cavity is formed inside the third filter frame 430.

[0060] It is worth mentioning that the first filter frame 410, the second filter frame 420 and the third filter frame 430 can be connected by means of snap-fit, screws, bolts, etc., which are not specifically limited here.

[0061] In addition, the filters on the first filter frame 410, the second filter frame 420 and the third filter frame 430 can be fixed by snapping, bonding or other methods.

[0062] See also Figure 6 As shown, the second filter frame 420 includes two outer filter brackets 421 and a filter (not shown in the figure) arranged on the outer filter bracket 421. The filter is arranged at the ventilation outlet of the outer filter bracket 421, and the two outer filter brackets 421 can be engaged with or separated from each other.

[0063] In the embodiment of the present application, one of the two outer filter brackets 421 is provided with a buckle 422, and the other is provided with an opening 423, and the buckle 422 and the opening 423 are both provided at the top of the outer filter bracket 421. When the buckle 422 is engaged in the opening 423, the two outer filter brackets 421 are engaged and connected.

[0064] For example, Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the second filter frame 420 includes a first outer filter support 421 and a second outer filter support 421, wherein the top of the first outer filter support 421 is provided with two openings 423, and the surface of the openings 423 is inclined toward the base. The second outer filter support 421 is provided with an extension portion extending toward the first outer filter support 421, and the side of the extension portion close to the base is provided with two buckles 422 extending downward and having the same structure. When the buckle 422 is engaged in the opening 423, the buckle 422 abuts against the inner wall of the opening 423, so that the first outer filter support 421 and the second outer filter support 421 are engaged with each other, so as to ensure the stability of the first outer filter support 421 and the second outer filter support 421, and prevent the first outer filter support 421 and the second outer filter support 421 from separating during the filtering process. When the first outer filter bracket 421 and the second outer filter bracket 421 need to be separated, since the surface of the opening 423 is tilted toward the base, when the extended part is bent upward, the buckle 422 can be disengaged from the opening 423, thereby separating the first outer filter bracket 421 from the second outer filter bracket 421.

[0065] It should be noted that the first outer filter bracket 421 and the second outer filter bracket 421 can also be provided with buckles 422 and openings 423 at other positions, for example, openings 423 and buckles 422 at the bottom, sides, etc., to achieve the combination and separation of the two outer filter brackets 421.

[0066] See also Figure 7 As shown, the tops of the first outer filter bracket 421 and the second outer filter bracket 421 are both provided with a filter air inlet 424 for allowing the gas in the drying barrel 200 to flow into the filter assembly 400. The filter air inlet 424 can be circular, and of course, other shapes can also be used, such as square, hexagonal, etc., which are not specifically limited here.

[0067] In addition, a filter screen is provided at the ventilation opening of the outer filter support 421 for filtering lint or other impurities, so as to prevent lint or other impurities from entering the base 120 .

[0068] In the examples of this application, please continue to refer to Figure 6 The two outer filter screen supports 421 each include an outer filter plate 4210 for mounting the filter screen, a filter top plate 4211 located at the top of the outer filter plate 4210, filter side plates 4212 located at opposite sides of the outer filter plate 4210, and a filter bottom plate 4213 located at the bottom of the outer filter plate 4210. The upper and lower ends of the filter side plates 4212 are respectively connected to the filter top plate 4211 and the filter bottom plate 4213. The filter top plate 4211, the outer filter plate 4210, the filter side plates 4212 and the filter bottom plate 4213 together form a second accommodating cavity.

[0069] The filter top plate 4211 may be an arc-shaped structure protruding toward the third filter frame 430, that is, bent toward the front support shell 110 to adapt to the shape of the front support shell 110. A plurality of filter air inlets 424 are provided on the filter top plate 4211 to reduce the size of a single filter air inlet 424 while ensuring the air intake. The filter air inlets 424 are arranged in multiple rows along the circumferential direction of the filter top plate 4211 to ensure that wire scraps or other impurities pass through or sink.

[0070] In addition, the filters on the first filter frame 410, the second filter frame 420 and the third filter frame 430 have different filtration densities. Usually, the third filter frame 430 usually uses a finer filter to perform preliminary filtration on the wire scraps.

[0071] Understandably, see Figure 1As shown, the air after drying the clothes in the clothes drying barrel 200 flows into the filter assembly 400 through the front support shell 110. The air flows into the filter air inlet 424 in the second filter frame 420 in advance, and the air after passing through the filter air inlet 424 enters the third filter frame 430 in advance, and then enters the second filter frame 420 after being filtered by the filter net of the third filter frame 430, and then enters the first filter frame 410 after passing through the filter net in the first filter frame 410, and then enters the base 120.

[0072] That is to say, the gas dried by the clothes drying barrel 200 first passes through the filter air inlet 424 on the second filter frame 420, and then passes through the filter screens on the third filter frame 430, the second filter frame 420 and the first filter frame 410 in sequence, so as to achieve the filtering effect of lint or other impurities.

[0073] After the filter assembly 400 has been working for a long time, a large amount of lint or other impurities are accumulated inside the filter assembly 400. According to the above description, since the filter on the third filter frame 430 pre-filters the gas, a large amount of lint is easily accumulated in the third accommodating chamber, resulting in a reduction in the amount of air flowing from the third filter frame 430 into the second filter frame 420 and the first filter frame 410, that is, a reduction in ventilation, and a reduction in the amount of air entering the base 120, thereby causing problems such as low drying air volume and low drying efficiency.

[0074] Therefore, in order to increase the gas flowing from the third filter frame 430 into the second filter frame 420 and the first filter frame 410 and reduce the clogging of the wire scraps, the dryer 10 also includes a collecting assembly, which includes a rotating component 510, which is arranged in the third accommodating chamber, and the rotating component 510 can rotate relative to the third filter frame 430, that is, the rotating component 510 can rotate in the third accommodating chamber. Figure 4 and Fig.11 As shown, during the rotation of the rotating part 510, the lint will rotate along with the rotating part 510, so as to collect the lint to one side of the third accommodating chamber, reduce the lint blocking the filter on the third filter frame 430, ensure the airflow entering the second filter frame 420 and the first filter frame 410, ensure the ventilation volume, and further ensure the drying effect of the clothes.

[0075] Among them, see Figure 6 and Fig.11As shown, in order to drive the rotating component 510 to rotate, the dryer 10 also includes a driving member 600, which is arranged in the front support shell 110. The driving member 600 corresponds to the rotating component 510. The rotating component 510 can rotate in the third accommodating chamber under the drive of the driving member 600, thereby driving the thread scraps in the third accommodating chamber to move along the rotation direction of the rotating component 510 to realize the collection of the thread scraps.

[0076] It is understandable that the driving member 600 can be connected to the rotating member 510 by a coupling, a gear, a latch, a pin, a key connection, a magnetic coupling, or the like.

[0077] In the embodiment of the present application, since the driving member 600 is disposed on the outside of the filter assembly 400, in order to ensure the filtering effect and the driving effect, the driving member 600 is connected to the rotating member 510 by means of a magnetic coupling connection.

[0078] It is understandable that the magnetic coupling connection between the driving member 600 and the rotating member 510 can also facilitate the user to take and place the filter assembly 400 separately, and the taking and placing of the filter assembly 400 is simple and convenient.

[0079] For example, Fig.11 As shown, the driving member 600 includes a driving motor and an output shaft, and the first magnetic coupler 700 is sleeved on the output shaft. The rotating component 510 includes a rotating member 511 and a coupling member 512. The rotating member 511 is extended in the length direction of the third filter frame 430, and one end of the rotating member 511 passes through the third filter frame 430 and is placed in the second accommodating chamber. One end of the rotating member 511 is set with a gap between the inner wall of the second filter frame 420, and the rotating member 511 is rotatably connected with the third filter frame 430; the other end of the rotating member 511 passes through the third filter frame 430, and the rotating member 511 located in the second accommodating chamber is provided with the above-mentioned coupling member 512, that is, the coupling member 512 is set in the second accommodating chamber. That is, the other end of the rotating member 511 passes through the third filter frame 430 in sequence and is connected with the coupling member 512. The coupling member 512 can abut against the inner wall of the second accommodating chamber, or can be set with a gap between the inner wall of the second accommodating chamber.

[0080] The coupling member 512 may also be a magnetic coupling, which may be plug-connected with the rotating member 511 or may be integrally formed with the rotating member 511. The coupling member 512 is magnetically coupled with the first magnetic coupling 700, and the power output by the driving motor may be transmitted to the coupling member 512 through the first magnetic coupling 700 on the output shaft, and the coupling member 512 drives the rotating member 511 to rotate at the same speed and rate as the output shaft, thereby rotating and collecting the wire scraps in the third accommodating chamber, reducing the blockage of the wire scraps, and improving the ventilation volume and drying efficiency.

[0081] In order to drive the wire scraps in the third accommodating chamber to be collected, Fig.11 As shown, the rotating member 511 includes a rotating shaft 5110 and a twisting piece 5111. The twisting piece 5111 is spirally wound on the rotating shaft 5110, and one end of the rotating shaft 5110 is provided with the coupling member 512. That is to say, the rotating shaft 5110 is driven by the coupling member 512 to rotate, thereby driving the twisting piece 5111 to rotate in the axial direction of the rotating shaft 5110. During the rotation process, the twisting piece 5111 can wind the wire scraps in the third accommodating chamber onto the twisting piece 5111, and through the rotation of the twisting piece 5111, the wire scraps are pushed to move in the axial direction of the rotating shaft 5110, thereby collecting the wire scraps in the third accommodating chamber to one side of the third accommodating chamber, reducing the blocking of the filter screen on the third filter screen frame 430, and increasing the ventilation volume.

[0082] It is worth mentioning that the rotating shaft 5110 and the twisting piece 5111 can be integrally formed to improve the tightness of the structure.

[0083] In addition, in order to facilitate the collection of wire scraps in the third accommodating chamber, a chip passing port is provided on one side of the third accommodating chamber, and this chip passing port passes through the third filter frame 430, the second filter frame 420 and the first filter frame 410 in sequence, so as to discharge the wire scraps in the third accommodating chamber through the chip passing port; this chip passing port is provided on one side of the first filter frame 410, the second filter frame 420 and the third filter frame 430 close to the base, that is, it is provided at the bottom of the first filter frame 410, the second filter frame 420 and the third filter frame 430, but is not limited to the bottom, for example, the side of the first filter frame 410, the second filter frame 420 and the third filter frame 430.

[0084] like Figure 4 As shown, the collection component also includes a collection box 520, and this collection box 520 can adopt a square or rectangular structure, and of course, other shapes, such as a circular or elliptical structure, can also be adopted. The collection box 520 is arranged on the side of the chip passing port close to the base, and the collection box 520 corresponds to the chip passing port. Among them, the twisting piece 5111 can push the wire scraps inside the third accommodating cavity to be collected to the chip passing port during the rotation of the rotating shaft 5110, and collect them into the collection box 520 through the chip passing port. The wire scraps brought out by the twisting piece 5111 are discharged into the collection box 520 through the chip passing port, so as to complete the collection of wire scraps, increase ventilation, and thus improve drying efficiency.

[0085] It is worth mentioning that the chip opening can be arranged on the side of the first filter frame 410 close to the driving member 600, or on the side of the first filter frame 410 away from the driving member 600. The specific design can be carried out according to different embodiments and is not specifically limited here.

[0086] In order to improve the collection efficiency of the wire scraps, the collection assembly further includes a collection fan 530, which is disposed in the front support shell 110 and is disposed on a side of the collection box 520 away from the filter assembly 400. The collection fan 530 is connected to the inside of the collection box 520, and the collection fan 530 can suck the wire scraps at the chip opening into the collection box 520. Figure 4 shown.

[0087] It is understandable that the air pressure in the collection box 520 can be formed into a negative pressure through the collection fan 530, and under the action of pressure and suction, the wire scraps at the chip outlet are collected into the collection box 520, thereby accelerating the collection of the wire scraps.

[0088] In addition, by collecting the lint with the strong suction of the collecting fan 530, most of the lint can be collected in the collecting box 520, and due to the strong suction, the density of the accumulated lint can be very large, and the filter assembly 400 can be manually cleaned at long intervals.

[0089] It is worth mentioning that in order to prevent the lint from entering the collecting fan 530 , filter cotton is provided at the connection between the collecting fan 530 and the collecting box 520 to protect the collecting fan 530 .

[0090] It should be noted that the collection box 520 is disposed on the front side of the front support shell 110 , and the collection box 520 can be taken out and placed without opening the door of the dryer 10 , so cleaning is simple and convenient.

[0091] In an embodiment of the present application, a heat pump system (not shown in the figure) may be provided inside the base 120. The heat pump system may include a compressor, a condenser, a throttling device, an evaporator and a circulating fan 800, etc. The evaporator, the condenser and the circulating fan 800 are arranged in sequence along the air flow direction of the circulating air duct 300, and the compressor, the condenser, the throttling device and the evaporator are connected in sequence by pipelines to form a refrigerant circulation pipeline, and the refrigerant circulation pipeline is filled with refrigerant medium.

[0092] When the heat pump system is running, the compressor pressurizes and heats the refrigerant and then sends it to the condenser. The high-temperature refrigerant exchanges heat with the air in the air duct at the condenser and is converted into low-temperature, low-pressure gas. The low-temperature, low-pressure gas is transported to the evaporator after passing through the throttling device. After entering the evaporator, it absorbs the heat of the high-temperature, humid gas flowing through the surface of the evaporator, then heats up and flows back to the compressor, completing the refrigerant flow cycle. At the same time, the air flow in the bottom air duct enters the drying barrel 200 from the rear cover 130 under the action of the circulating fan 800. When the high-temperature gas passes through the drying barrel 200, it comes into contact with the wet clothes and becomes humid hot gas. The humid hot gas enters the bottom air duct from the filter air inlet 424 of the filter assembly 400 and is blown toward the evaporator, where it exchanges heat with the low-temperature refrigerant medium. The humid hot gas is condensed and dehumidified to form dry air. After passing through the condenser, the dry air exchanges heat with the high-temperature refrigerant medium in the condenser to form high-temperature dry air. The high-temperature dry air continues to flow and enters the drying barrel 200 again from the rear cover 130, forming an air flow cycle, and takes away moisture in the clothes through the circulating flow of air, thereby drying the clothes.

[0093] In this embodiment, since the hot and humid air is condensed and cooled in the evaporator to form condensed water, a water collecting pan for receiving the condensed water is also provided in the circulating air duct 300 to collect the condensed water. In this application, the configuration of the housing 100, the clothes drying barrel 200 and the heat pump system can be configured with reference to the prior art, and will not be described in detail here.
